[jira] [Updated] (HBASE-11165) Scaling so cluster can host 1M regions and beyond (50M regions?)

["Andrew Purtell (JIRA)" <ji...@apache.org>]

Andrew Purtell updated HBASE-11165:
-----------------------------------

    Attachment: HBASE-11165.zip

Attached as HBASE-11165.zip is a list of the counts and aggregate sizes of live objects in an otherwise idle regionserver after loading 10000 regions (e.g. 1M regions might be hosted on 100 servers), 241 MB of heap in total. I found some of it surprising.

> This discussion issue comes out of "Co-locate Meta And Master HBASE-10569" and comments on the doc posted there.
> A user -- our Francis Liu -- needs to be able to scale a cluster to do 1M regions maybe even 50M later.  This issue is about discussing how we will do that (or if not 50M on a cluster, how otherwise we can attain same end).
> More detail to follow.
